I do still wonder where we're going with that plot point.
In the special episodes, we see that Lizana already fucks all these random men(Delivery guy, Principal, Janitor next?) voluntarily, so I kinda don't see the point in the Police Woman forcing or blackmailing her, unless we actually build up to her husband finding out about everything.
At this point in the story, I don't see how Lizana x "disposable older man of the month" could give us anything new or exciting?
I'd vastly prefer if the story went back to further develop the sexual and romantic chemistry between Lizana and Ramon like in the first 3 chapters.
